Default Lining up timing dots help.....

Ok, my cam has been in my car for a year, no issues, except too little clearance, I just found out. I just took off my timing cover. The double roller timing chain has 2 dots on it, which one is to match the cam dot?
I still have the oil pump on so I can only see the inner dot, it is NOT lined up. The inner dot is lined up is on the keyway. Is the dot on the keyway the one that is supposed to line up? Or the dot on the outer sprocket? Since my heads are off too, I can tell then when the cam dot is at 6:00 piston #1 is at TDC so I think its on coreclty, but I am trying to verify.
This may solve my clearance issue, being that I have been driving for a year with .011.
If the timing is off, why does my car run so well and dyno so high?

Dyno

Dave,

You'll change it to where it should be and it probably won't dyno as high or run as well.

I'm fairly certain it is correct, but I figure before I buy a new cam I'll ask. I hope I did it wrong, but its doubtful. The directions on the timing chains absolutely suck.

The inner dot is for the keyway the outer is the timing dot.

Ok, so at TDC on #1 the inner dot and the keyway will be at about 2:00.
that is how it is.

You did fine. the dot that's supposed to line up with the cam sprocket dot is on the very tip of the cam sprocket. the dot that you can see on the sprocket with the oil pump on is to indicate where the key thingie goes

Exactly... On crank gears with multiple keyways, the keyway will be marked with a certain mark (some use shapes such as circles, triangles, squares, others may use a dot, + sign, and a - sign), then there will be a second mark near the teeth that match the one marking the keyway; that is the one you line up with the mark on the cam gear. Trust me, if it was off and ligned up with the wrong mark you would know it. I suspect from your description that it is correct or at least as close as it can be with out degreeing it.
